HOME_NET includes all locally attached Networks
When selecting a passlist to define the HOME_NET the HOME_NET always contains the locally attached networks of all interfaces(except wan). Even if the Local Networks Add firewall Locally-Attached Networks to the list (excluding WAN). option is not checked in the passlist configuration. This is different as the expected behavior.
In a scenario where your want to protect a local network from other local networks you might consider only the network from the interface suricata is running on as HOME_NET and everything else EXTERNAL.
